NFC: trf7970a: Document the 'irq-status-read-quirk' DT property
The mechanism for specifying that the trf7970a being used by the driver has the "IRQ Status Read" erratum has been changed to a device tree property ('irq-status-read-quirk'). Document the new device tree property. Signed-off-by: Mark A. Greer <> Signed-off-by: Samuel Ortiz <>
